Estimating the term…
An object of the present invention is to improve the functionality of a noise reducer adapted to perform an active noise reduction process. The object is achieved by a noise reducer 300 comprising at least one microphone 310 connected to a noise controller 320, and at least one loudspeaker 330 connected to the noise controller 320. The microphone 310 is arranged at the loudspeaker 330, and the noise controller 320 is adapted to perform an active noise reduction process. An event detector 340 is connected to the noise controller 320 and adapted to send an event 10 detection signal to the noise controller 320, wherein the event detection signal comprises information regarding an external event. The noise controller 320 is further adapted to analyse the event detection signal and to adapted to control the active noise reduction process in dependence of an outcome of the analysis of the event detection signal.
A noise reducer comprising:
A method in a noise reducer for controlling an active noise reduction process, wherein the noise reducer comprises at least one microphone connected to a noise controller, and at least one loudspeaker connected to the noise controller, wherein the microphone is arranged at the loudspeaker, and wherein the noise controller is adapted to perform the active noise reduction process, the method comprising:
